Fun fact: posting photos with metadata intact can leak your exact location. If a CDN doesn’t explicitly strip it, images from iPhones and other devices may include GPS data and device details. I’ll expand this app, so you can handle metadata removal locally without relying on CDN for that.

Instead of creating another FFmpeg wrapper, I built this using WebCodecs, which is up to 67x faster than FFmpeg WASM. Run your videos through this before posting on Nostr. It cuts size by 50–90% with minimal quality loss, saves CDN bandwidth, and makes posts load instantly. https://nostr-compress.vercel.app

Thanks for sharing. This means I should make metadata removal more selective, stripping sensitive fields while preserving non-sensitive data, in line with Blossom’s recommendations.
